Alternative Processes: Vandyke Brown prints

Alternative Processes: Vandyke Brown Prints

Instructed by Cathie McCormick Ph.D.

No need for film negatives for this alternative process printing process. We use the ultraviolet light of the sun to develop an emulsion brushed on cotton paper. The negative is a transparency printed on an office laser printer. Use our available “negatives” to print a photo, or place objects on the paper to create a photogram.

The cotton paper is prepared with a solution of starch before applying the light-sensitive material with a brush. Once the emulsion dries, your composition is put in place and exposed to sunlight. Since the solution does not respond to fluorescent light, this process does not require a darkroom or safe light. In this three-hour workshop, you will create several of your own compositions, experience preparing the paper for exposure, and see your images come to life during the post-exposure washing process.

If you wish to bring your own 8.5 x 11” transparency “negative,” here is a link to the tutorial.

This workshop is weather dependent, in the case of rain an alternative date will be announced.
